What to do if you haven’t much time
- Deadhead perennials, bedding and basket plants and roses to encourage more flowers. Apply high potash fertiliser (e.g. tomato food) to enable the growth of lots more flowers.
- Mow regularly if the grass is growing. If the soil is very dry, raise the blades to leave the grass longer, which helps it to stay alive in a drought. Trim the egdes of the lawn – it makes such a difference!
